Abstract
A driver includes a boost converter, a pulse width modulator controlling the boost converter, and a timer controlling the pulse width modulator. The timer, such as a digital counter, causes the pulse width modulator to produce narrow pulses unless or until the end of a period is reached, at which point the pulse width modulator is not controlled by the timer.
